Abstract

A transparent display device using rotation-based persistence of vision includes: an opaque display unit that displays first images; a transparent display unit that includes image display bars, which are positioned outside the opaque display unit and on each of which a plurality of light emitting elements are mounted, and a display bar driving unit which rotates the image display bars, the transparent display unit displaying second images which are viewed to overlap the first images by persistence of vision based on rotation of the image display bars; and a display casing that accommodates both the opaque and transparent display units in a state where the transparent display unit is positioned outside the opaque display unit, the display casing having a sight window through which the first images and the second images are viewed at a preset region.

First claim

The invention claimed is:

1. A transparent display device using rotation-based persistence of vision, comprising:
an opaque display unit that displays first images;
a transparent display unit that includes image display bars, which are positioned outside the opaque display unit and on each of which a plurality of light emitting elements are mounted, and a display bar driving unit which rotates the image display bars, the transparent display unit displaying second images which are viewed to overlap the first images by persistence of vision based on rotation of the image display bars; and
a display casing that accommodates both the opaque and transparent display units in a state where the transparent display unit is positioned outside the opaque display unit, the display casing having a sight window through which the first images and the second images are viewed at a preset region,
wherein the transparent display unit includes a plurality of image display bars which are arranged around a display bar rotating shaft at regular angles such that eccentricity is inhibited from being generated during rotation of the image display bars.

2. The transparent display device using rotation-based persistence of vision according to claim 1 ,
wherein the transparent display unit includes
display bar connecting members which connect all of the plurality of image display bars to be separated from the display bar rotating shaft in order to form a predetermined mounting space in which the opaque display unit is mounted as the image display bars rotate, and

image boards which are provided at the display bar connecting members to rotate together with the image display bars and provide image signals of the first images which are to be displayed on the image display bars.

3. The transparent display device using rotation-based persistence of vision according to claim 2 ,
wherein the display bar connecting members have respective board mounting portions which project from the display bar connecting members and at which the respective image boards are mounted, and
wherein each of the display bar connecting members has a dummy portion at a portion at which the board mounting portion is not formed, the dummy portion projecting to have a shape corresponding to the board mounting portion in order to inhibit eccentricity from being generated during rotation.

4. The transparent display device using rotation-based persistence of vision according to claim 1 ,
wherein the opaque display unit includes a display panel which electronically displays the first images.

5. The transparent display device using rotation-based persistence of vision according to claim 1 ,
wherein the opaque display unit includes
a rotary wheel which has a plurality of the first images formed into a pattern in a circumferential direction, and
a wheel driving unit which drives the rotary wheel.

6. The transparent display device using rotation-based persistence of vision according to claim 5 ,
wherein a wheel rotating shaft of the rotary wheel and the display bar rotating shaft of the image display bar are positioned on the same axial line.

7. The transparent display device using rotation-based persistence of vision according to claim 5 ,
wherein the display bar rotating shaft is formed into a penetrating shape such that the wheel rotating shaft of the rotary wheel is inserted and fitted into the display bar rotating shaft, and
wherein the transparent display device using rotation-based persistence of vision further comprises an inner bearing that is provided between the wheel rotating shaft and the display bar rotating shaft in a state where the wheel rotating shaft is inserted into the display bar rotating shaft such that rotation of the wheel rotating shaft is secured with respect to the display bar rotating shaft.

8. The transparent display device using rotation-based persistence of vision according to claim 5 ,
wherein the display casing includes a shaft support which is formed into a penetrating shape such that the display bar rotating shaft is inserted and fitted into the shaft support, and
wherein the transparent display device using rotation-based persistence of vision further comprises an outer bearing that is provided between the shaft support and the display bar rotating shaft in a state where the display bar rotating shaft is inserted into the shaft support such that rotation of the display bar rotating shaft is secured with respect to the shaft support.

9. The transparent display device using rotation-based persistence of vision according to claim 5 ,
wherein the display bar driving unit is positioned on one side of the display casing and drives the display bar rotating shaft of the image display bar, and the wheel driving unit is positioned on the other side of the display casing and drives the rotary wheel.

10. The transparent display device using rotation-based persistence of vision according to claim 5 ,
wherein the display casing includes
shaft supports which are formed on both sides of the display casing and into which the display bar rotating shaft is inserted, the display bar rotating shaft being formed into a penetrating shape into which the wheel rotating shaft is inserted and fitted such that the wheel rotating shaft is inserted into the display bar rotating shaft,
a first support member which is provided at a shaft support formed on one side of the display casing and supports the display bar rotating shaft at the shaft support such that the display bar rotating shaft is positioned at a center of the shaft support, and
a second support member which is provided at a shaft support formed on the other side of the display casing and supports the display bar rotating shaft at the shaft support such that the wheel rotating shaft is positioned at a center of the shaft support.

11. The transparent display device using rotation-based persistence of vision according to claim 10 ,
wherein the first support member has a first power transmitting portion which transmits power of the display bar driving unit to rotate the display bar rotating shaft by rotating the first support member coupled to the display bar rotating shaft.

12. The transparent display device using rotation-based persistence of vision according to claim 10 ,
wherein the second support member has a second power transmitting portion which transmits power of the display bar driving unit to rotate the wheel rotating shaft by rotating the second support member coupled to the wheel rotating shaft.

13. A transparent display device using rotation-based persistence of vision, comprising:
an opaque display unit that includes a rotary wheel which displays first images and a wheel driving unit which drives the rotary wheel;
a transparent display unit that includes image display bars, which are positioned outside the opaque display unit and on each of which a plurality of light emitting elements are mounted, and a display bar driving unit which rotates the image display bars, the transparent display unit displaying second images which are viewed to overlap the first images by persistence of vision based on rotation of the image display bars;
a display casing that accommodates both the opaque and transparent display units in a state where the transparent display unit is positioned outside the opaque display unit, the display casing having a sight window through which the first images and the second images are viewed;
a first support member which is provided on one side of the display casing and supports the wheel rotating shaft of the rotary wheel such that the rotary wheel is rotatable in the display casing; and
a seco
